Refess has the best Hit Points and Healing of all the colors. Its units have a mix of offensive and defensive abilities, usually focusing on supporting other units and bypassing enemy protections. They have good SP generation, but also they tend to have high SP consumption.

Refess Card Files don't like to see their units go to the Cemetery. Rather than temporary gain, they go for stability, delivering their damage turn after turn. The weak point of Refess is its speed.

Lawtia is probably the most extreme of the colors, but it can also be the most powerful. If a Lawtia Iczer wins with only 1 LP remaining, his first thought is "all that matters is that I won." In fact, you could say that if he had too much LP to spare, then he wasn't dueling in the spirit of Lawtia. A Lawtia Iczer sacrifices his own units for immediate gain, then capitalizes on that gain to dominate his opponent.

Lawtia units have excellent offensive capabilities, unique powers, gain big bonuses during the night, and have the ability to burn away the enemy's SP. Because of all of these factors, timing is absolutely vital for Lawtia. Lawtia units have above average speed and below average HP.

Gowen can be summed up in one word: explosive. With more SP-effecent pure fighters than anyone else, you'll have a solid fighting force on the field quick. On top of that, Gowen has more inexpensive high AGI choices than any other color and Rank Up, the ability to level cards for more fighting ability.

Gowen Grimoire cards usually do straight damage and plenty of it, while support units give strong bonuses to AT. Gowen has the speed to take control of the field early, and the power to keep it.

Falkow rewards card combos the way Lawtia rewards timing. It's known as the thinking man's sphere, but it has the potential to dominate any game. The strong points of Falkow are AGI manipulation and card Return.

Since a returned card can't hurt anything, and going first means killing a unit before it even gets to attack, these are vital abilities that make up for Falkow's low HP. Falkow card skills are versatile, so there's a lot of room to leverage combos to control your enemy.
